Cracks or sores in the corner of the mouth can be rather annoying, like a paper cut — small, and irritating. Fancy medical terms for this condition include "angular stomatitis," "angular cheilitis," or "perleche."

A number of different things can be behind the development of such cracks:

* yeast infections
* vitamin deficiencies (vitamin B2 or riboflavin)
* iron-deficiency anemia (low red blood cells due to too little iron)
* allergic reaction to some substance (particularly products used on the lips, such as lip gloss/stick/balm, and even dental care/oral hygiene products, such as toothpaste)
* poorly fitting dentures (or no teeth or no dentures at all)
